Anaesthesia · Intravenous Anaesthetic Agents (Propofol, Ketamine, Etomidate, Barbiturates)

According to the manufacturer's recommendation, an opened vial of propofol infusion must be discarded after:

  • A 48 hours
  • B 24 hours
  • C 12 hours
  • D 6 hours
Correct answer: D. 6 hours

Explanation

Propofol is presented as a lipid emulsion containing soybean oil, glycerol and egg phosphatide with no added preservative, and the formulation actively supports bacterial and fungal growth. Slow draw-up from a single vial over several hours has caused documented postoperative infection outbreaks. Hence strict asepsis at draw-up and disposal of any unused contents within 6 hours of opening are mandatory.
